How It Works & Privacy Architecture

A client-side utility built for absolute financial privacy.

Zero Server Uploads • Total Privacy

Financial statements and demat accounts contain deeply sensitive personal identifiers, bank details, and investment portfolios. This utility is engineered with a strict zero-knowledge architecture:

Runs 100% In Your Browser: All spreadsheet parsing, header alignment, unmerging, and CSV serialization occur entirely inside your browser's local memory (RAM).
No Network Transmission: Your files and transaction records are never uploaded to any remote server or third-party service.
Volatile Storage: Data exists only while the tab is open. Refreshing the browser instantly purges all parsed data from memory.
Offline Capable (PWA): Once loaded, this web app functions completely offline without an active internet connection.

Extensible Parsing Engine

The parser automatically decodes the complex merged-cell layout of HDFC Demat reports:

Locates the dynamic table header row regardless of pre-header statement metadata.
Forward-fills merged ISIN identifiers across multi-row transaction blocks.
Extracts Scrip names from header rows and associates them with corresponding trade rows.
Normalizes dates and numbers to produce clean, spreadsheet-ready CSV exports.

Open Source & Auditable
